摘要:
A primer composition comprises (A) an organosilicon compound having different alkoxy groups in its molecule, (B) a tetraalkoxytitanium, (C) an acid and water, and (D) an organic solvent. The composition shows excellent adhesion properties to fluororesin coating materials, acrylic resin coating materials, etc. When applied to the surface of a metal coated with such a coating material, the primer composition is capable of providing a remarkably enhanced adhesion, for example, between a silicone elastomer and the coated metal.

摘要:
A primer composition is proposed which is capable of greatly improving the adhesive bonding between a substrate surface, in particular, coated with a paint containing a fluorocarbon resin, urethane resin or acrylic resin as the vehicle, and a room temperature-curable silicon rubber composition, in particular, of the type curable by the condensation reaction. The primer composition is a homogeneous solution obtained by dissolving, in an organic solvent, a guanidino group-containing organosilicon compound, such as 3-(tetramethylguanidino)propyl trimethoxy silane, and a so-called silane coupling agent, such as 3-mercaptopropyl trimethoxy silane, in a specified proportion.

The present invention relates to an optical sender applicable to WDM (wavelength division multiplexing), and a primary object of the present invention is to prevent interchannel crosstalk in WDM. The optical sender includes a light source for outputting a light beam, an optical modulator for modulating the light beam in accordance with a main signal to output an optical signal, and a unit for shutting down the optical signal when receiving at least one of a power alarm relating to on/off of power supply and a wavelength alarm relating to the wavelength of the light beam.

The invention aims to reduce an error occurring due to the mounting condition of an acceleration sensor. In the case of a two-axis sensor, an angle θ is calculated from outputs (x′, y′) that the acceleration sensor produces when known accelerations (x, y) are applied, and the angle θ is stored in a storage device contained in a casing in which the acceleration sensor is housed. In the case of a one-axis sensor, the ratio of the magnitudes of accelerations is stored. The acceleration detected by the acceleration sensor is compensated by using the value stored in the storage device.

A rotary disc for use in a rotary encoder includes a signal generation section having a pattern formed thereon to generate a signal indicative of a rotational angle/phase. The signal generation section has a peripheral surface, which is provided with a linear portion usable as an indicator indicative of the rotational angle/phase represented by the signal generation pattern on the signal generation section. A robot hand is employed to hold the linear portion and attach it through an attachment portion of the rotary disc to a rotor shaft of a motor.

The invention aims to suppress or prevent the vibration that can occur due to the intervention of a low-rigidity part between detector and rotating body. An angular acceleration sensor for detecting the rotational angular acceleration of a rotating body is provided, and an angle/angular speed command value is compensated in accordance with the value of the angular acceleration.
